Beamer 超寬頁面在顯示器之間重疊

Question

我正在嘗試使用pgfpages具有創建超寬頁面選項的軟體包\setbeameroption{previous slide on second screen=left}來利用多個顯示器。這是我在 PDF 閱讀器中得到的結果。

由於「開始」圖示未與垂直框對齊，這表示左側預覽的一部分將顯示在投影機顯示器上（因為啟動圖示左側的所有內容都會顯示在投影機上）。有些人可能會說這與 LaTeX 無關，但是使用 LaTeX 可以完成一個很好的解決方法；如果我可以在兩張投影片之間插入一個空白區域（在垂直框位置），那麼兩張投影片將被分開，任何重疊將顯示為空白區域，而不是另一張投影片內容的一部分。如果可以自訂空白區域的背景，使其與左側投影片的背景混合（如果它不是白色），那就太好了。

\newlength{\widthTextMarginLeft}
\setlength{\widthTextMarginLeft}{1.5mm}

\setlength{\widthTextMarginRight}{2mm}
\setbeamersize{text margin left=\widthTextMarginLeft, text margin right=\widthTextMarginRight}
\newlength{\sidebarWidth}
\setlength{\sidebarWidth}{0.3\paperwidth}
\setbeamersize{sidebar width left=\sidebarWidth, sidebar width right=0cm}

\setbeamercovered{transparent=30}
\setbeamersize{description width=0mm}

Answer 1

previous slide on second screen您可以定義一個自訂佈局並根據需要移動頁面，而不是使用重新定義的佈局（我用 標記了要調整值的兩個位置<-...）：

\setlength{\widthTextMarginLeft}{1.5mm}
\newlength{\widthTextMarginRight}
\setlength{\widthTextMarginRight}{2mm}
\setbeamersize{text margin left=\widthTextMarginLeft, text margin right=\widthTextMarginRight}
\newlength{\sidebarWidth}
\setlength{\sidebarWidth}{0.3\paperwidth}
\setbeamersize{sidebar width left=\sidebarWidth, sidebar width right=0cm}

\setbeamercovered{transparent=30}
\setbeamersize{description width=0mm}

\usepackage{blindtext}

\usepackage{pgfpages}

\setbeamercolor{background canvas}{bg=green}
